Validation of sink rates of longlines measured by two different methods
with bottles averaged 0.13 ± 0.02 m.s-1 compared to 0.21 ± 0.07 m.s-1 recorded by TDRs. This difference ... difficult and unreliable with bottles. Bottles had a higher failure rate (51 – 68 %) than TDRs (> 90 ... %), for example, with string becoming entangled or bottles vanishing from sight. We recommend while ...

Estimates of local biomass, including estimates of uncertainty, for Antarctic (Dissostichus mawsoni) and Patagonian (Dissostichus eleginoides) toothfish in research blocks in Subareas 48.2, 48.6, 58.4 and 88.3
Abstract: This paper includes updated local biomass estimates of toothfish populations with ... at WG-SAM-16 with revisions to the CPUE-by-seabed area parameter values agreed at WG-SAM-17. The ... higher CPUE-by-seabed area estimates has also resulted in a greater overlap in confidence intervals with ...
